User Defined Types

Lycia allows developers to define their own data types. These can be based either on primitive data types (such as INTEGER), or complex types such as structures and arrays.

User defined types can also be derived from database objects, and even structured types defined within the RDBMS. User-defined data types can be reused throughout the program eliminating the need to repeat the definition of core business objects.

Derivation / Inheritance

It is also possible to derive new sub-types from these user defined data types. For example, if a record is defined as a type containing properties of a person, such as first name and last name, it is possible to create an employee type that shares these properties but also has additional properties, such as an employee number.
